篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了配置IPV6网络相关的知识，希望对你有一定的参考价值。
一、 实验要求及思路：
1. 使用eNSP模拟器搭建试验环境（拓扑如下），
2. 核心网配置ospf v3路由协议，R2和R3配置VRRP ipv6
3. IP地址采用ipv6版本，PC机采用手动配置IPv6地址2001:DB8:C703:4416::4/64
4. 要求配置全网互通，VRRP实现冗余备份
二、 实验拓扑:
三、 IP地址规划：
R1 | G0/0/0 | 12::1/64 |
G0/0/1 | 13:1/64 | |
LO 0 | 11::1/64 | |
R2 | G0/0/0 | 23::2/64 |
G0/0/1 | 2001:DB8:C703:4416::2/64 | |
G0/0/2 | 12::2/64 | |
R3 | G0/0/0 | 23::3/64 |
G0/0/1 | 2001:DB8:C703:4416::3/64 | |
G0/0/2 | 13::3/64 |
四、 配置文件及步骤：
1. R1的配置
1) IP配置
<Huawei>sy
[Huawei]sysname R1
[R1]ipv6 //开启路由器IPv6报文转发功能
[R1]int g0/0/0
[R1-GigabitEthernet0/0/0]ipv6 enable //开启路由器接口IPv6报文转发功能
[R1-GigabitEthernet0/0/0]ipv6 address 12::1 64 //配置接口的全球单播ipv6地址
[R1-GigabitEthernet0/0/0]undo shut
[R1]int g0/0/1
[R1-GigabitEthernet0/0/1]ipv6 enable
[R1-GigabitEthernet0/0/1]ipv6 address 13::1 64
[R1-GigabitEthernet0/0/1]undo shut
[R1-GigabitEthernet0/0/1]int lo 0
[R1-LoopBack0]ipv6 enable
[R1-LoopBack0]ipv6 address 11::1 64
[R1-LoopBack0]display ipv6 int b
2) 路由配置
[R1]ospfv3 //启动OSPFv3，进入OSPFv3视图
[R1-ospfv3-1]router-id 1.1.1.1 //配置Router ID
[R1-ospfv3-1]q
[R1]int g0/0/0
[R1-GigabitEthernet0/0/0]ospfv3 1 area 0 //在接口上启用
Ospfv3，并让其属于区域0
[R1-GigabitEthernet0/0/0]int g0/0/1
[R1-GigabitEthernet0/0/1]ospfv3 1 area 0
[R1-GigabitEthernet0/0/1]int lo 0
[R1-LoopBack0]ospfv3 1 area 0
[R1-LoopBack0]q
<R1>display ospfv3 peer
<R1>display ospfv3 routing
2. R2的配置
1) IP配置
<Huawei>sy
[Huawei]sysname R2
[R2]ipv6
[R2]int g0/0/2
[R2-GigabitEthernet0/0/2]ipv6 enable
[R2-GigabitEthernet0/0/2]ipv6 address 12::2 64
[R2-GigabitEthernet0/0/2]undo shut
[R2-GigabitEthernet0/0/2]int g0/0/0
[R2-GigabitEthernet0/0/0]ipv6 enable
[R2-GigabitEthernet0/0/0]ipv6 address 23::2 64
[R2-GigabitEthernet0/0/0]undo shut
[R2-GigabitEthernet0/0/0]int g0/0/1
[R2-GigabitEthernet0/0/1]ipv6 enable
[R2-GigabitEthernet0/0/1]ipv6 address fe80::2 link-local //手动配置接口的链路本地地址
[R2-GigabitEthernet0/0/1]undo shut
[R2-GigabitEthernet0/0/1]ipv6 addr 2001:DB8:C703:4416::2 64 //配置接口的全球单播ipv6地址
[R2-GigabitEthernet0/0/1]undo shut
[R2-GigabitEthernet0/0/1]undo ipv6 nd ra halt //开启RA消息发布的功能，以便客户机获得路由设备的RA报文消息
[R2]display ipv6 int b
2) 路由配置
[R2]ospfv3
[R2-ospfv3-1]router-id 2.2.2.2
[R2-ospfv3-1]q
[R2]int g0/0/2
[R2-GigabitEthernet0/0/2]ospfv3 1 area 0
[R2-GigabitEthernet0/0/2]int g0/0/1
[R2-GigabitEthernet0/0/1]ospfv3 1 area 0
[R2-GigabitEthernet0/0/1]int g0/0/0
[R2-GigabitEthernet0/0/0]ospfv3 1 area 0
[R2-GigabitEthernet0/0/0]q
[R2]display ospfv3 peer
[R2]display ospfv3 routing
3) 做ipv6 vrrp
[R2]int g0/0/1
[R2-GigabitEthernet0/0/1]vrrp6 vrid 1 virtual-ip fe80::1 link-local //创建备份组，并配置虚拟ipv6地址（飘移地址）为链路本地地址
[R2-GigabitEthernet0/0/1]vrrp6 vrid 1 virtual-ip 2001:DB8:C703:4416::1 //创建备份组，并配置虚拟ipv6地址（飘移地址）为全球单播地址
[R2-GigabitEthernet0/0/1]vrrp6 vrid 1 priority 115 //设置优先级为115（默认是100，监听的上行口每挂一个就减10，这里要求当G0/0/2和G0/0/0都挂了的时候才被BACKUP抢占），让路由器R2成为master负责转发数据流量
[R2-GigabitEthernet0/0/1]vrrp6 vrid 1 preempt-mode timer delay 0 //设置抢占时间为0，即立即抢占，默认就是0可不输入这条命令
[R2-GigabitEthernet0/0/1] vrrp6 vrid 1 track int g0/0/2 //监听上行口
[R2-GigabitEthernet0/0/1] vrrp6 vrid 1 track int g0/0/0 //监听上行口
[R2]display vrrp6 b
3. R3的配置
1) IP配置
<Huawei>sy
[Huawei]sysname R3
[R3]ipv6
[R3]int g0/0/2
[R3-GigabitEthernet0/0/2]ipv6 enable
[R3-GigabitEthernet0/0/2]ipv6 address 13::3 64
[R3-GigabitEthernet0/0/2]undo shut
[R3-GigabitEthernet0/0/2]q
[R3]int g0/0/0
[R3-GigabitEthernet0/0/0]ipv6 enable
[R3-GigabitEthernet0/0/0]ipv6 address 23::3 64
[R3-GigabitEthernet0/0/0]undo shut
[R3]int g0/0/1
[R3-GigabitEthernet0/0/1]ipv6 enable
[R3-GigabitEthernet0/0/1]ipv6 address fe80::3 link-local
[R3-GigabitEthernet0/0/1]ipv6 addr 2001:DB8:C703:4416::3 64
[R3-GigabitEthernet0/0/1]undo shut
[R3-GigabitEthernet0/0/1]undo ipv6 nd ra halt
[R3]display ipv6 int b
2) 路由配置
[R3]ipv6
[R3]ospfv3
[R3-ospfv3-1]router
[R3-ospfv3-1]router-id 3.3.3.3
[R3-ospfv3-1]q
[R3]int g0/0/2
[R3-GigabitEthernet0/0/2]ospfv3 1 a
[R3-GigabitEthernet0/0/2]ospfv3 1 area 0
[R3-GigabitEthernet0/0/2]int g0/0/1
[R3-GigabitEthernet0/0/1]ospfv3 1 area 0
[R3-GigabitEthernet0/0/1]int g0/0/0
[R3-GigabitEthernet0/0/0]ospfv3 1 area 0
[R3-GigabitEthernet0/0/0]q
[R3]display ospfv3 peer
[R3]display ospfv3 routing
3) 做ipv6 vrrp
[R3]int g0/0/1
[R3-GigabitEthernet0/0/1]vrrp6 vrid 1 virtual-ip fe80::1 link-local
[R3-GigabitEthernet0/0/1]vrrp6 vrid 1 virtual-ip 2001:DB8:C703:4416::1
[R3-GigabitEthernet0/0/1]vrrp6 vrid 1 preempt-mode timer delay 0
[R3]display vrrp6 b
五、 结果验证 :
Ping R1环回口的
跟踪路由
将R2的g0/0/2和g0/0/0都shut,先查看vrrp6的状态
再跟踪到R1环回口11：1的路由
在实验过程中曾出现master路由器R2在上行 口down且优先级比R3小的时候， vrrp状态依然是master，同时R3也是master，这就有了2个master，
原因可能是：一是延迟，二是模拟器问题
